St. Anthony Posted January 26 Share Posted January 26 Hello all, I am working in western Washington and have been hitting the beaches. I think I have found some petrified palm or limb cast of degraded palm. Any input is appreciated. I will be shipping some things back home and would like to have other eyes on it. Thank you all in advance. The last photo is trying to show the wood texture. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 26 Share Posted January 26 Looks like weathered limestone to me, but let's see what locals say.......... 3 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

DPS Ammonite Posted January 26 Share Posted January 26 Put some acid on it to see if it really is limestone. I see some contorted layering that makes be think that it might be a metamorphic rock . Show us some clear up close photos of the rock that shows individual grains. Also the pattern of wear suggests that is a harder rock than limestone. I also see no typical limestone weathering, dissolution by acid rain. 1 My goal is to leave no stone or fossil unturned.

St. Anthony Posted January 26 Author Share Posted January 26 Thank you DPS Ammonite. Muratic or Hydrochloric is there a preference? I will need to pick some up. Here are some photos as close as I could get. The stone is 21cm x 21 cm x 8 cm and weighs 4 kg. Thank for your time and expertise. Link to comment Share on other sites More sharing options...
St. Anthony Posted January 27 Author Share Posted January 27 DPS Ammonite. The acid did not effervesce on the piece. I think these are better shots of the individual grains. Thanks again for your time. 1 Link to comment Share on other sites More sharing options...
DPS Ammonite Posted January 27 Share Posted January 27 I think that this also might be a metamorphic rock such as schist similar to your rock from Washington in your recent post. Does the rock have a sheen from mica? 2 My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

MarcoSr Posted January 27 Share Posted January 27 I don't see any evidence of petrified wood cell structure in your closeup pictures. You might need higher magnification to see it, if it is there. Sometimes pieces are just casts of completely decayed/incinerated wood filled in by minerals. Also, in the mineralization process of the wood itself, the cell structure can be completely lost. I don't think the piece is petrified wood. Marco Sr. 1 "Any day that you can fossil hunt is a great day."

St. Anthony Posted January 27 Author Share Posted January 27 Thank you DPS Ammonite, Tidgy's Dad and MarcoSR. I am learning a lot from you and appreciate it. I hit the beach and started gathering what looked like petrified wood based on shape more than structure. Now I know it is more involved than that. Thanks for your time. I have a few more rocks to sort out so I will have a few more posts. Thanks so much for helping a newbie along. I find this fascinating. Take care 1 Link to comment Share on other sites More sharing options...
St. Anthony Posted January 27 Author Share Posted January 27 Would you all look at this piece? Different looking than my other stuff. Found on same beach area. Apparently. 16 cm x 6 cm x 3 cm. Thanks for looking. Link to comment Share on other sites More sharing options...
